Crocosmia plant named ‘Scorchio’

ABSTRACT

A new and distinct cultivar of  Crocosmia  plant named ‘Scorchio’, characterized by its upright plant habit; strong, sturdy and resistance to lodging; moderately vigorous to vigorous growth habit; freely flowering habit; numerous and relatively large and upward-facing yellow orange, orange, orange red and red-colored flowers; and good garden performance and winter hardiness.

Botanical designation: Crocosmia X hybrida.

Cultivar denomination: ‘SCORCHIO’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Crocosmia plant, also referred to as Montbretia, botanically known as Crocosmia X hybrida and hereinafter referred to by the name ‘Scorchio’.

The new Crocosmia plant is a product of a planned breeding program conducted by the Inventor in Carisbrook, Newport, The Isle of Wight, United Kingdom. The objective of the breeding program is to create new upright and strong Crocosmia plants with large attractive upward-facing flowers, a long flowering period and winter hardiness.

The new Crocosmia plant originated from a cross-pollination made by the Inventor in Carisbrook, Newport, The Isle of Wight, United Kingdom on Jul. 10, 2007 of two unnamed seedling selections of Crocosmia X hybrida, not patented. The new Crocosmia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Carisbrook, Newport, The Isle of Wight, United Kingdom on Aug. 14, 2009.

Asexual reproduction of the new Crocosmia plant by divisions in a controlled greenhouse environment in Carisbrook, Newport, The Isle of Wight, United Kingdom since the spring of 2010 has shown that the unique features of this new Crocosmia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Crocosmia have not been observed under all possible combinations of environmental conditions and cultural conditions. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Scorchio’. These characteristics in combination distinguish ‘Scorchio’ as a new and distinct Crocosmia plant:

-   -   1. Upright plant habit; strong, sturdy and resistance to         lodging.     -   2. Moderately vigorous to vigorous growth habit.     -   3. Freely flowering habit.     -   4. Numerous and relatively large and upward-facing yellow         orange, orange, orange red and red-colored flowers.     -   5. Good garden performance and winter hardiness.

Plants of the new Crocosmia differ primarily from plants of the parent selections in the following characteristics:

-   -   1. Plants of the new Crocosmia are more freely flowering than         plants of the parent selections.     -   2. Plants of the new Crocosmia have larger flowers than plants         of the parent selections.     -   3. Plants of the new Crocosmia are more winter hardy than plants         of the parent selections.

Plants of the new Crocosmia can be compared to plants of Crocosmia X hybrida ‘Zambesi’, not patented. In side-by-side comparisons, plants of the new Crocosmia differ primarily from plants of ‘Zambesi’ in flower color as plants of the new Crocosmia have more distinct and pronounced flower color markings than plants of ‘Zambesi’. In addition, plants of the new Crocosmia have larger flowers than plants of ‘Zambesi’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants of the new Crocosmia grown during the summer in an outdoor nursery in Hillegom, The Netherlands.
